COIv/IBINE) SINK STRANER, AND DISGSAL ENVELGPE.

Application filed November 15,` 1923.

To aZZ whom t may camera:

Be it known that I, DONALD lV. ADAMS, a citizen of the United State-s, residing at Chicago, in the county of Cook and State of, lllinois, have invented certa-in new and useful Improvements in Combined Slnk Strainers and Disposal Envelopes, of which the following is a specification.

This in cntion relates to sink strainers or other like utensils for receiving refuse and separating it from` its lquid constituent, and has for its primary object to provide such a utensil with a liner, which while insuring proper drainage will retain the solid constituent and provide a cheap and convenient envelope through means of which it may be disposed of.

Another object is to provide a cheap but efiicient supporting frame with which the liner may be assembled in developing a straining receptacle, and one which will be especially adapted to receive and support a liner made of relatively thin material, for instance, paper, not only along marginal lines of the liner but at intermediate portions of its area as well, and particularly beneath its perforated bottom and without obstructing the drainage through the bottom.

The invention proceeds upon the principle of providing a series of liners of paper or other material equivalent thereto with respect to the purpose to be served by the invention, and having a perforated bottom and side walls upstanding from said bottom; and adapting said liners replaceably or interchangeably to a frame of wire or other open work having a supporting bottom and lateral confines upstanding therefrom corresponding in internal dimensions substantially to the external dimensions of the liners, so that when a liner is assembled with the frame a substitute drainage receptacle is afforded, and when it becomes necessary to dispose of accumulation of solid mat-- ter in such receptacle, the liner may be removed with such matter and discarded with the same as a. compliance with city ordinances requiring such refuse to be envelopcd, a fresh liner being placed in the frame instead Of the one remo-ved.

Preferably, the liner carries closing flaps in hinging relation to the upper Inargins of its sides, and in position to be held folded against the sides by the frame so long as the receptacle is open, and preferably the frame Serial No. 674,311.

is made up of upper and lower rims conforming substantially to a horizont-al section or horizontal sections of the liner, and these rinis have their corresponding members connected by intermediate vertical members to permanently unite them and form the lateral confines of the frame, while the lower rim has intern'eciate bridging bars between its sides that afford support for the perforated bottom of the liner without obstructing its drainage.

In the accompanying drawing- Figure l is a pcrspective of the complete strainer when in open or receiving condition.

Figure 12 is a similar view of the fra-me alone.

Figure 3 is a perspcctive view of the liner removed and closed to form a disposa-l cnvelope.

A represents the liner, and B the frame. Liner A comprises in its preferred embodiment a bottom l of tri-angular form having perforations 2 which permit escape of liquid while holding back solid constituents of sink refuse; side walls 3, 4, and 5 upstanding from the bottom l; and closing flaps 6, 7, and 8 hingedly related to the upper margins 3a, 4a, 5a of the side walls and of dimensions which. while adapting them to form a complete closure of the open receptacle, will also permit them to lie against the outer faces of the side walls when the receptacle is being filled.

The frame B consists, in its preferred embodiment, of -a lower rim 9 composed of rails 9a, 9b, 9 related as a triangle or other geometrical figure in Correspondence with the horizontal section of the liner; an upper rim 10 composed of rails lOa, lOb, 100, similarly related, as the sides of a triangle; the vertical uniting rods lla, ll, llc which relate the two rim members at a fixed distance apart and form the lateral confines of the i the liner A, without ohstructingzj drainag'e through periiorations 2. Feet l-P, 14", MF raise the bottom above the surtt'ace upon which the straner stands.

Having assembled a` perforated liner A. With the frame B as suggested in Fignre l, the resultant reeeptacle may be use-d after the manner of an ordinary sink strainer, the fiaps 6, 7, 8, being introduced between the liner walls 8, 4, 5, and the intermediat-e lateral confine bars 13, lb, lQC. Then it is desired to dispose ot the accumulation in the receptacle A, B, the fiaps 5, 7, 8 may be extracted and gathered together to serve as a handle for lift-mg the liner' from the trame. Such litting e'fect Will 'tacilitate Withdrawal ot' the liner from the trame in that it draws the corners ot' the liner away 'from the Upper rim 10. The 'flaps may now be pinned or otherwise secnred together to complete envelopment ot the contents, after which the package may be deposited in the fire, the garbage pa-il, or other place ot disposal. A new liner Will be assembled With the fraine to adapt the receptacle tor 'turther use.

I claim:

1. A sink stra-iner comprising` a rene'vvable envelope and a snpporting and protecting` cage therefor; said envelope being ormed With a bottom and With side walls angularly related vto said bottom and to one another; and the cage being constructed With top and bottom trames providing continuous protecting eurbs positioned respeetively at and conorming to the top and bottom margins ot the envelope, also With corner bars detining the positions ot' said 'trames and guardng the corners of the envelope and With intermediatevertcal bars protecting intermediate portions ot the envelope sides.

2. In a sink strainer, the combination ot a cage constructed With a snpporting,` bott-om having' a tri-angular marginal 't'rame 1and cross bars extending between sides'of such franie and with a top tramev of triangular form. and vertical bars Connecting said trames and spacing them apart; and an envelope of paper or the like constructed With a. bottom through which it rest-s on the bottom of the cage, conforming snbstantially to the marginal frame of said bot-tom and with upsta-nding side walls which terminate approximately in coincidence-With the marginal sides oi: the Upper iframe and therebj,7 adapt the Upper marginal rame to serve als deining and protecting bars or the open top of the envelope.

Signed at Chicago, Illinois, this eighth day of November', 1923.
